3011-34-5 4-hydroxy-3-nitrobenzaldehyde InChI=1/C7H5NO4/c9-4-5-1-2-7(10)6(3-5)8(11)12/h1-4,10 benzaldehyde, 4-hydroxy-3-nitro- CAS 3011-34-5 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 3011-34-5 4-hydroxy-3-nitrobenzaldehyde InChI=1/C7H5NO4/c9-4-5-1-2-7(10)6(3-5)8(11)12/h1-4,10 benzaldehyde, 4-hydroxy-3-nitro-.

3011-34-5 4-hydroxy-3-nitrobenzaldehyde InChI=1/C7H5NO4/c9-4-5-1-2-7(10)6(3-5)8(11)12/h1-4,10 benzaldehyde, 4-hydroxy-3-nitro- (CAS 3011-34-5), molecular formula C7H11NO4 and molecular weight 173.17 g/mol, is a CATO reference standard with documented purity and traceability.

Owing to an amino-acid-derived structure, an amide group, a hydroxyl group, an ether linkage, 3011-34-5 4-hydroxy-3-nitrobenzaldehyde InChI=1/C7H5NO4/c9-4-5-1-2-7(10)6(3-5)8(11)12/h1-4,10 benzaldehyde, 4-hydroxy-3-nitro- is typically white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 173.17 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.

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.
