Acetaminophen Related Compound D - USP CRS is a reference standard of acetanilide (N-phenylacetamide), a known impurity of acetaminophen (paracetamol) that differs from acetaminophen by lacking the para-hydroxyl group. Beyond its role as a reference standard, acetanilide itself serves as an intermediate for sulfa drugs and azo dyes, a stabilizer for hydrogen peroxide, and a rubber accelerator. It is used for analytical calibration, method validation, and impurity profiling in pharmaceutical testing. This compound ensures accuracy in HPLC, GC, and spectroscopic assays for drug development and quality control. CAS 103-84-4 | Molecular formula CH₃CONHC₆H₅ | Molecular weight 135.16 g/mol | Store at ambient temperature in a tightly sealed container. Signal word: Warning (H302: harmful if swallowed; handle with standard lab precautions). Molekula supplies Acetaminophen Related Compound D - USP CRS from research to bulk quantities with full documentation and ISO 9001:2015 traceability.
