Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 2065-37-4 1,4-Naphthalenedione, 2-bromo- (9CI) 1,4-Naphthoquinone, 2-bromo- (8CI) 2-Bromo-1,4-naphthoquinone 3-Bromo-1,4-naphthoquinone NSC 401097.

2065-37-4 1,4-Naphthalenedione, 2-bromo- (9CI) 1,4-Naphthoquinone, 2-bromo- (8CI) 2-Bromo-1,4-naphthoquinone 3-Bromo-1,4-naphthoquinone NSC 401097 (CAS 2065-37-4) is a high-purity analytical reference standard with the molecular formula C10H11BrO2 and a molecular weight of 243.10 g/mol.

The molecular framework of 2065-37-4 1,4-Naphthalenedione, 2-bromo- (9CI) 1,4-Naphthoquinone, 2-bromo- (8CI) 2-Bromo-1,4-naphthoquinone 3-Bromo-1,4-naphthoquinone NSC 401097 (C10H11BrO2) is characterized by a carboxylic acid group, a hydroxyl group, an ether linkage, bromine substitution, an aromatic ring system. In reversed-phase chromatography, its retention is governed primarily by its high hydrophobicity (logP), which provides a practical basis for HPLC-UV/DAD or LC-MS method development. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

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.
