Chemical Structure
Description
The occurrence of 24589-99-9 Benzoic acid, 3-formyl-4-hydroxy-, methyl ester Isophthalaldehydic acid, 4-hydroxy-, methyl ester (6CI,8CI) 4-10-00-03622 (Beilstein Handbook Reference) BRN 1426212 5-Carbomethoxysalicylaldehyde 4-Hydroxyisophthalaldehyde acid methyl ester Methyl 3-formyl-4-hydroxybenzoate Methyl 4-hydroxyisophthalaldehydate is closely related to a carboxylic acid group, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
24589-99-9 Benzoic acid, 3-formyl-4-hydroxy-, methyl ester Isophthalaldehydic acid, 4-hydroxy-, methyl ester (6CI,8CI) 4-10-00-03622 (Beilstein Handbook Reference) BRN 1426212 5-Carbomethoxysalicylaldehyde 4-Hydroxyisophthalaldehyde acid methyl ester Methyl 3-formyl-4-hydroxybenzoate Methyl 4-hydroxyisophthalaldehydate (CAS 24589-99-9) is a high-purity analytical reference standard with the molecular formula C9H14O4 and a molecular weight of 186.21 g/mol.
Owing to a carboxylic acid group, a hydroxyl group, an ether linkage, 24589-99-9 Benzoic acid, 3-formyl-4-hydroxy-, methyl ester Isophthalaldehydic acid, 4-hydroxy-, methyl ester (6CI,8CI) 4-10-00-03622 (Beilstein Handbook Reference) BRN 1426212 5-Carbomethoxysalicylaldehyde 4-Hydroxyisophthalaldehyde acid methyl ester Methyl 3-formyl-4-hydroxybenzoate Methyl 4-hydroxyisophthalaldehydate is typically white to off-white crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 186.21 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
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.
