7147-89-9 4-Chloro-6-nitro-m-cresol Phenol, 4-chloro-5-methyl-2-nitro- m-Cresol, 4-chloro-6-nitro- EINECS 230-461-5 NSC 28451 CAS 7147-89-9 chemical structure

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 7147-89-9 4-Chloro-6-nitro-m-cresol Phenol, 4-chloro-5-methyl-2-nitro- m-Cresol, 4-chloro-6-nitro- EINECS 230-461-5 NSC 28451.

7147-89-9 4-Chloro-6-nitro-m-cresol Phenol, 4-chloro-5-methyl-2-nitro- m-Cresol, 4-chloro-6-nitro- EINECS 230-461-5 NSC 28451 (CAS 7147-89-9) is a high-purity analytical reference standard with the molecular formula C7H12ClNO3 and a molecular weight of 193.63 g/mol.

The molecular framework of 7147-89-9 4-Chloro-6-nitro-m-cresol Phenol, 4-chloro-5-methyl-2-nitro- m-Cresol, 4-chloro-6-nitro- EINECS 230-461-5 NSC 28451 (C7H12ClNO3) is characterized by an amide group, a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine substitution. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.

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

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.
