Sodium Propylparaben or Sodium Propyl p-hydroxybenzoate
CAS Number: 35285-69-9
Molecular Formula: C10H11NaO3
Molecular Weight: 202.18
Sodium Propylparaben or Sodium Propyl p-hydroxybenzoate
Propylparaben Sodium USP NF Grade Specifications
Propylparaben Sodium contains not less than 98.5 percent and not more than 101.5 percent of C10H11NaO3, calculated on the anhydrous basis.
Completeness of solution: One g of it, dissolved in water, meets the requirement.
Identification:
A: Dissolve 0.5 g in 5 mL of water, acidify with hydrochloric acid, and filter the resulting precipitate. Wash the precipitate with water, and dry it over silica gel for 5 hours: the IR absorption spectrum of a mineral oil dispersion of it exhibits maxima only at the same wavelengths as that of a similar preparation of USP Propylparaben.
B: Ignite about 0.3 g, cool, and dissolve the residue in about 3 mL of 3 N hydrochloric acid. A platinum wire dipped in this solution imparts an intense, persistent yellow color to a nonluminous flame.
pH: between 9.5 and 10.5, in a solution (1 in 1000).
Water: not more than 5.0%.
Chloride: A 0.2-g portion shows no more chloride than corresponds to 0.10 mL of 0.020 N hydrochloric acid (0.035%).
Sulfate: A 0.25-g portion shows no more sulfate than corresponds to 0.30 mL of 0.020 N sulfuric acid (0.12%).
