[0021] (1) Reagent selection: acetonitrile: Merck, batch number: SBK5734; phosphoric acid: Sinopharm, batch number: 20170929.
[0022] (2) Sample selection: Propranolol hydrochloride (API) provided by Yunyang (batch number 180101, 170201, 170202); 1-naphthol: Aladdin, batch number: K1717022; naphthalene glycidyl ether: LGC, batch number: 43050702, content 99.6%; Impurity A: LGC, lot number: 43010801; Impurity B: LGC, lot number: 79125; Impurity C: LGC, lot number: 66021.

[0024] Solution preparation: 1-naphthol and glycidyl ether are classified as Type 2 impurities by ICHM7. The maximum daily dose of propranolol hydrochloride is 240mg. The impurity limit is calculated according to the TTC method, 1.5μg / day÷240mg / day=6.25ppm, Check the quality standards of propranolol hydrochloride in various national pharmacopoeias. Only the Chinese Pharmacopoeia stipulates that 1-naphthol must not exceed 300ppm. JP17, USP41, and EP9.0 do not stipulate the limits of 1-naphthol and naphthalene glycidyl ether. According to the requirements of current regulations and Strict control strategy, the limit of 1-naphthol and glycidyl ether is proposed to be 6.25ppm, in order to make the impurity in the API controllable within 6.25ppm, the API concentration is 50mg / ml, and the impurity limit concentration is 0.3125μg / ml for analysis method development.
[0025] Diluent: The diluent consists of acetonitrile and water in a volume ratio of 1:1;
