2022 New Products
Each year CIL adds many new products for environmental, food, water, and exposure analysis to our inventory. Most items included in this new-product listing are in stock and available for standard delivery, though some items still in the production process may be listed as “inquire.” Please contact us for complete product availability.
Cannabinoids
(-)-Δ9-Tetrahydrocannabinol (THC) is a major cannabinoid compound produced by the cannabis plant. THC is regulated by a variety of state and federal laws due to its psychoactive effects. Tetrahydrocannabivarin (THCV) is a homologue of tetrahydrocannabinol (THC) and does not exhibit psychoactive effects. It may have potential use for weight loss and/or management of obesity and type 2 diabetes, as it has been shown anecdotally to suppress the appetite and increase satiety.
Per- and Polyfluorinated Substances (PFAS)
Increased interest in short- and ultra-short-chain PFAS has led to the development of C3 carboxylic acid PFPrA. As part of our continuing improvement process, we have adjusted several carboxylates and sulfonates to their salt form, or an alternate salt form, leading to easier, cleaner purification and formulation. DONA is now available as a free acid standard, while several previously developed native mixtures have been updated to include components now in their salt form. Expanding interests have led to CIL developments for fluorotelomer alcohol (FTOH) and fluorotelomer acid (FTA) standards. As with the fluorotelomer sulfonates (FTS), our labeled fluorotelomer compounds utilize the preferred 13C2/D4 (M+6) labeling scheme. New efforts have led to the development of small-chain perfluoro mono-ether acids PMPA and PEPA. A linear isomer-only FOSA is now added to complement our stock mixed isomer standard. CIL has formulated the US EPA Method 8237 native mixture and should soon also have the Method 8327 labeled mixture (comparable to PFAC-24PAR and MPFAC-24ES, respectively). CIL has prepared a new set of native and labeled mixtures for PFOS, PFOA, and PFHxS to meet growing demand for this set of important PFAS compounds. CIL also now offers convenient native and labeled mixtures of the four commonly analyzed FTS compounds (4:2, 6:2, 8:2, and 10:2 FTS).

Industrial Chemicals
6PPD-Quinone, which is an ozonation byproduct of rubber tire additive 6PPD, has been shown to be highly toxic to coho salmon. CIL initially developed a phenyl-13C6-labeled standard and has most recently added a new 13C12-labeled standard. The two labeling options can be used in combination to offer further improvement of precision for quantitative analysis. 3,3’-Dichlorobenzidine is classified as a probable human carcinogen by the United States Environmental Protection Agency (US EPA). It was mainly used in producing dyes and pigments, though it is no longer authorized for use in the US.

Priority Pollutants
Polystyrene-D8 represents our first stable isotope-labeled standard to assist researchers in the rapidly growing field of microplastics research using pyrolysis GC-MS analysis. Ethylene oxide (EtO) is a gas used in the food industry as a preservative and fumigant to control insects and is a classified carcinogen and mutagen with concerns for human exposure and toxicity. Due to airfreight restrictions for the neat material, CIL recently developed EtO and 2-chloroethanol standard solutions which meet transportation exemption quantities and allow for normal airfreight delivery.

Phthalates and Phthalate Metabolites
Terephthalate esters have been gaining use as phthalate replacement products as increased scrutiny and restrictions on phthalates occur.
CIL has previously synthesized and offered mono-2-ethylhexyl terephthalate standards for human exposure studies and has recently produced a standard for the native parent compound, bis(2-ethylhexyl) terephthalate.

Pesticides and Pesticide Metabolites
Neonicotinoids continue to attract a lot of attention, yet pyrethroids are widely used in both agricultural and residential settings, and their metabolites are also of concern. CIL is the only commercial source of chrysanthemum dicarboxylic acid, both in native and stable isotopelabeled forms, and several other pyrethroid metabolites are now available in MTBE for compatibility with related compounds that are prone to decomposition in other polar solvents. Diuron is on the UCMR 1 program Screening Survey (List 2 contaminant).
