This week's mix is broader than last week’s PFAS-heavy set: this batch includes two benzalkonium-style quaternary ammonium standards from HPC Standards, a pair of chiral pinocembrin reference materials, a food-matrix CRM for baby cereal, an arsenic speciation CRM for apple juice, and a widely used inorganic synthesis reagent from Fluorochem. Together they give Novachem a neat cross-section of environmental hygiene, food safety, trace-element QA, and general lab support.
HPC Standards quaternary ammonium markers
Benzyldimethyloctylammonium chloride (BAC 8) (HPC Standards) – View product
BAC 8 is a useful short-chain quaternary ammonium marker for labs validating disinfectant residue, formulation, or environmental monitoring methods. It gives QC teams a clean reference point when they need to distinguish individual benzalkonium homologues rather than treating BAC as a single bulk analyte.
Benzyldimethyloctadecylammonium chloride (BAC 18) (HPC Standards) – View product
BAC 18 extends the same homologue set into the longer-chain end, which matters for chromatographic separation work and surfactant profiling. Labs checking sanitizer blends, surface residues, or extraction recoveries can use it to tighten method specificity across the BAC family.
Food and beverage matrix CRMs
Baby Cereal Coarse Rice Flour (National Research Council Canada / LGC Standards) – View product
This baby-food matrix CRM is a strong fit for infant nutrition and contaminant labs that need a realistic cereal substrate rather than a solvent-only spike. It is especially handy for method verification where matrix effects, digestion behaviour, or trace-element recovery have to be demonstrated in a product that looks like the real sample stream.
Arsenic Species in Apple Juice (NIST / LGC Standards) – View product
A dedicated apple juice arsenic speciation CRM gives food safety labs a high-value tool for validating HPLC-ICP-MS or equivalent workflows against a genuine beverage matrix. It is the sort of material that helps prove both species separation and reporting confidence when customers or regulators ask for something stronger than a neat calibration mix.
Research and synthesis support
Sodium hydride (60% in Paraffin oil) (Fluorochem Ltd) – View product
A dependable sodium hydride stock line is a practical add for synthetic and medicinal chemistry teams running deprotonation or alkylation steps in-house. It broadens the catalogue beyond pure analytical standards and gives R&D customers another reason to keep routine reagent purchasing with Novachem.
Chiral reference additions
(R)-Pinocembrin (HPC Standards) – View product
The R-enantiomer of pinocembrin is relevant for natural products, nutraceutical, and chiral method-development work where stereochemistry changes the analytical picture. Adding the isolated enantiomer helps customers move beyond total-pinocembrin screening into proper enantiomeric identification and comparison.
(S)-Pinocembrin (HPC Standards) – View product
Pairing the S-enantiomer with the R-form gives chromatographers and phytochemical researchers a complete small set for retention matching and optical purity checks. It is a tidy example of a niche but genuinely useful line item for customers building out more advanced chiral workflows.
