SLU-PP-332 Oral

Vad är SLU-PP-332?

SLU-PP-332 is a synthetic small molecule from the acylhydrazine family and is not a peptide: it has no amino acid sequence, but a fixed-defined chemical structure with the molecular formula C₁₈H₁₄N₂O₂ and a molecular weight of approximately 290.3 g/mol. The compound is known by CAS number 303760-60-3 (PubChem CID 5338394) and bears the systematic name 4-hydroxy-N'-(naphthalene-2-ylmethylene)benzohydrazide.

The structure consists of a hydroxylated benzohydrazide unit connected to a naphthalene-2-yl group via a hydrazone bridge (C=N). Two properties make the substance suitable as reference material in analytical work: the extensive conjugate system of naphthalene ring and hydrazone bridge provides strong UV absorption, making detection with HPLC-UV simple and sensitive, and the low molecular weight yields a mass spectrum that is easy to interpret in LC-MS. The hydrazone bridge itself is a classic target in stability studies, because the C=N bond can hydrolyze into the two starting fragments under the influence of moisture, light, and pH shift.

Tillämpningar i laboratoriesammanhang

Within analytical chemistry, SLU-PP-332 occurs in the following in vitro research areas, among others:

• Content determination where the reference substance serves as a reference point for quantitative HPLC-UV determinations on samples with unknown content.
• Identitetsverifiering where the retention time, UV spectrum, and mass spectrum of a sample are compared with those of the reference material.
• Utveckling och validering av analytiska metoder (HPLC, LC-MS) whereby the linearity, repeatability, detection limit, and determinability limit of a method are established.
• Stability and degradation study in which the behavior of the hydrazone bridge is monitored under standardized conditions of temperature, humidity, and light, and the formed degradation products are separated chromatographically.

Specifikationer

Form, hantering och förvaring

The material is supplied as a solid tablet in a pack of one hundred, in three concentrations: 250 mcg, 500 mcg, and 1 mg per tablet. Because the substance is weighed per unit, less weighing is required in an analytical setup, and the variability between samples is lower than when manually weighing a loose powder. Those wishing to work with powder form in a setup can switch to the freeze-dried vial variant of the same compound.

Keep the packaging closed, dry, and at room temperature, protected from direct light and moisture, and out of reach of unauthorized persons. Hydrazone compounds are sensitive to prolonged exposure to moisture; a closed package keeps the material stable over the duration of a measurement series. Apply customary laboratory precautions and dispose of residual material in accordance with applicable guidelines.

Analytisk kvalitet

For solid units such as tablets, quality is expressed as content per unit, rather than as an HPLC purity percentage as is customary for loose powders. In analytical work, the identity and content of the starting material determine how interpretable each measurement is: a deviation in the starting sample affects the entire measurement series. Our SLU-PP-332 is therefore supplied with a controlled composition and accompanying analytical documentation, so that the starting material can be verified before a measurement series begins.
