Description

Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.

536-40-3 Benzoic acid, p-chloro-, hydrazide (8CI) Benzoic acid, 4-chloro-, hydrazide (9CI) 4-Chlorobenzohydrazide p-Chlorobenzhydrazide 4-Chlorobenzhydrazide p-Chlorobenzohydrazide p-Chlorobenzoic acid, hydrazide 4-Chlorobenzoic acid, hydrazide p-Chlorobenzoic hydrazide p-Chlorobenzoyl hydrazide 4-Chlorobenzoyl hydrazide p-Chlorobenzoylhydrazine 4-Chlorobenzoylhydrazine EINECS 208-632-0 NSC 54990 (CAS 536-40-3) is a high-purity analytical reference standard with the molecular formula C7H13ClN2O and a molecular weight of 176.64 g/mol.

Owing to an amide group, a hydroxyl group, an ether linkage, chlorine substitution, 536-40-3 Benzoic acid, p-chloro-, hydrazide (8CI) Benzoic acid, 4-chloro-, hydrazide (9CI) 4-Chlorobenzohydrazide p-Chlorobenzhydrazide 4-Chlorobenzhydrazide p-Chlorobenzohydrazide p-Chlorobenzoic acid, hydrazide 4-Chlorobenzoic acid, hydrazide p-Chlorobenzoic hydrazide p-Chlorobenzoyl hydrazide 4-Chlorobenzoyl hydrazide p-Chlorobenzoylhydrazine 4-Chlorobenzoylhydrazine EINECS 208-632-0 NSC 54990 is typically white to off-white crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 176.64 g/mol — guide the selection of appropriate sample preparation and analytical techniques. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.

The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
