Methyl Orange

Product Code : SCL-LC-12289

The Methyl Orange Indicator Reagent is an acid-base indicator used for supervised chemistry experiments, titration endpoint detection, pH-range demonstrations, and qualitative classroom analysis. It is suitable for schools, colleges, chemistry laboratories, science departments, institutional tenders, distributors, and educational procurement buyers.

Product Description

Methyl Orange from Science Lab Supplies is intended for controlled educational and laboratory use where a visible acid-base indicator is required. The exact physical form, concentration, grade, pack size, batch number, shelf life, SDS, COA, and regulatory documents must be confirmed before quotation or publication.

Methyl orange is commonly represented as C₁₄H₁₄N₃NaO₃S. It is an azo dye indicator that shows a red colour in acidic conditions and yellow-orange colour in higher pH conditions. This listing is for laboratory-use methyl orange only, not food, cosmetic, medical, dyeing, supplement, or consumer use.

Key Features

• Acid-base indicator: supports supervised titration and pH demonstration work.
• Clear transition range: commonly used around pH 3.1-4.4 for endpoint observation.
• Formula reference: methyl orange sodium salt is represented as C₁₄H₁₄N₃NaO₃S.
• Teaching-lab relevance: useful for acid-base lessons, indicator comparison, and titration practice.
• Form verification required: powder, crystals, solution strength, or solvent must be checked from the final label.
• Safety-led use: SDS review is required before handling, weighing, preparing solutions, or disposal.
• Documentation-led procurement: SDS, COA, batch number, grade, and shelf-life details should be verified before use.

How to Use the Methyl Orange

1. Read the current SDS, label, and institutional risk assessment before use.
2. Confirm whether the supplied product is powder, crystals, or ready-to-use solution.
3. Wear suitable PPE, including lab coat, gloves, and eye protection.
4. If supplied as solution, add only the drops specified in the approved titration method.
5. If supplied as solid, prepare indicator solution only by trained personnel using the written SOP.
6. Observe the endpoint under adequate lighting and record the colour change clearly.
7. Close the container immediately after use to reduce contamination or evaporation.
8. Dispose of used solutions according to institutional chemical-waste rules.

Safety note: Use Methyl Orange only in supervised laboratory procedures. Do not ingest, inhale dust or vapour, use as a textile dye, use medically, or issue for unsupervised student handling.

Care & Maintenance

• Store tightly closed in a cool, dry, ventilated chemical-storage area.
• Keep away from food items, unlabelled containers, incompatible chemicals, and unnecessary light or moisture exposure.
• Use clean dispensing tools and avoid contaminating the original bottle or pack.
• Maintain SDS, COA, batch number, grade, concentration, pack size, and shelf-life records.

Frequently Asked Questions

What is Methyl Orange used for in chemistry labs?

Methyl Orange is used as an acid-base indicator for supervised titration, endpoint detection, pH-range demonstrations, and indicator comparison practicals.

What colour does Methyl Orange show in acid?

Methyl Orange commonly appears red in acidic conditions and changes toward yellow-orange above its transition range.

What is the pH range of Methyl Orange?

The commonly referenced transition range is about pH 3.1-4.4. The exact range should be confirmed from the supplied formulation and COA.

What is the formula of Methyl Orange?

The formula of methyl orange sodium salt is C₁₄H₁₄N₃NaO₃S. Its CAS number is 547-58-0.

Is Methyl Orange suitable for school chemistry labs?

Yes. It is suitable for supervised school and college chemistry laboratories when trained staff control dispensing, titration use, storage, and disposal.

Is Methyl Orange supplied as powder or solution?

The supplied form is not confirmed. It may be procured as a solid indicator or solution, so the final label, quotation, SDS, and COA must be checked.
