Hypromellose Phthalate or Hydroxypropyl Methycellulose Phthalate or HPMC-P SDS of Manufacturers
Synonyms: Hypromellose Phthalate or Hydroxypropyl Methycellulose Phthalate or HPMC-P
CAS Number: 9050-31-1, EINECS EC Number: 232-674-9 or 618-567-3, FEMA: ----,
Specifications of Hypromellose Phthalate USP NF Grade:
DEFINITION
Hypromellose Phthalate is a monophthalic acid ester of hydroxypropyl methylcellulose. It contains methoxy (-OCH3 ), hydroxypropoxy (-OCH2CHOHCH3 ), and phthalyl (o-carboxybenzoyl, C8H5O3 ) groups. It contains NLT 21.0% and NMT 35.0% of phthalyl groups, calculated on the anhydrous basis.
IDENTIFICATION
A. Infrared Absorption: Do not dry specimens.
Phthalyl Content: To pass the test.
Acceptance criteria: 21% to 35% of phthalyl groups on the anhydrous basis.
Residue on Ignition: NMT 0.20%
Chloride and Sulfate, Chloride:
Sample solution: Dissolve 1.0 g in 40 mL of 0.2 N sodium hydroxide, add 1 drop of phenolphthalein and add 2 N nitric acid dropwise, with stirring, until the red color is discharged. Add an additional 20 mL of 2 N nitric acid with stirring. Heat on a water bath, with stirring, until the gel-like precipitate formed becomes granular. Cool the mixture, and centrifuge. Separate the liquid phase and wash the residue with three successive 20-mL portions of water, separating the washings by centrifuging. Dilute the combined liquids with water to 200 mL, mix, and filter.
Standard solution: Treat 0.50 mL of 0.01 N hydrochloric acid with 10 mL of 0.2 N sodium hydroxide, add 7 mL of 2 N nitric acid, and dilute with water to 50 mL.
Acceptance criteria: A 50-mL portion of the Sample solution shows no more chloride than the Standard solution (0.07%).
Limit of Free Phthalic Acid:
Acceptance criteria: NMT 1.0%
Water Determination: NMT 5.0%
Viscosity-Capillary: To pass the test.
Acceptance criteria: 80% to 120% of that indicated by the label.
Packaging and Storage: Preserve in tight containers.
Labeling: Label it to indicate its viscosity and nominal phthalyl content.
Specifications of Hypromellose Phthalate BP Ph Eure Grade:
DEFINITION
Hydroxypropylmethylcellulose phthalate.
Monophthalic acid ester of hypromellose, containing methoxy (-OCH3), 2-hydroxypropoxy (-OCH2CHOHCH3) and phthaloyl (o-carboxybenzoyl C8H5O3) groups.
CHARACTERS
Appearance: White or almost white, free-flowing flakes or granular powder.
Solubility: Practically insoluble in water, soluble in a mixture of equal volumes of acetone and methanol and in a mixture of equal volumes of methanol and methylene chloride, very slightly soluble in acetone and in toluene, practically insoluble in anhydrous ethanol.
IDENTIFICATION
Infrared absorption spectrophotometry.
Preparation Dissolve 40 mg in 1 mL of a mixture of equal volumes of methanol and methylene chloride; spread 2 drops of this solution between 2 sodium chloride plates, then remove one of the plates to evaporate the solvent.
Comparison hypromellose phthalate CRS.
TESTS
Free phthalic acid: To pass the test.
Limit: -- phthalic acid: not more than 0.4 times the area of the corresponding peak in the chromatogram obtained with the reference solution (1.0 per cent).
Chlorides: Maximum 0.07 per cent.
Water: Maximum 5.0 per cent, determined on 0.500 g.
Sulfated ash: Maximum 0.2 per cent, determined on 1.0 g.
Apparent viscosity: 80 per cent to 120 per cent of the nominal value.
Solubility: 0.2 g does not dissolve in 0.1 M hydrochloric acid but dissolves quickly and completely in 100 mL of phosphate buffer solution pH 6.8 with stirring.
Phthaloyl groups: Typically 21.0 per cent to 35.0 per cent (anhydrous substance).
