Powder | [Uses]
2-Hydroxy-1-naphthaldehyde is used in Merrified-type synthesis to deterime free amino acid groups in polymers. | [Definition]
ChEBI: 2-hydroxy-1-naphthaldehyde is a member of the class of naphthaldehydes that is naphthalene-1-carbaldehyde substituted by a hydroxy group at position 2. Active core of sirtinol (CHEBI:73158). It is a member of naphthaldehydes and a member of naphthols. | [Purification Methods]
Crystallise the aldehyde from EtOH (1.5mL/g), aqueous EtOH, aqueous AcOH (m 84o), EtOAc or H2O. [Russell & Lockhart Org Synth Coll Vol III 463 1955, Beilstein 8 H 143, 8 I 564, 8 II 171, 8 III 1108, 8 IV 1160.] |
